Description

Technical Field

[0001] This utility model relates to the field of transformer bushings, specifically a transformer bushing lead clamping structure. Background Technology

[0002] Transformer bushings are the main insulation devices outside the transformer box. The leads of the transformer windings must pass through the insulating bushings to insulate between the leads and between the leads and the transformer casing. They also serve to fix the leads. Depending on the voltage level, insulating bushings come in various forms, such as pure porcelain bushings, oil-filled bushings, and capacitor bushings.

[0003] In existing technology, transformer leads must pass through transformer bushings to ensure insulation distance between the leads and ground and the tank, preventing short circuits or current leakage. However, after passing through the transformer bushings, the transformer leads are prone to displacement or detachment due to vibration or external forces during power transmission, thereby reducing the stability of the leads. Utility Model Content

[0007] Preferably, the surface of the first gear is provided with a first hollow groove, the surface of the support plate is provided with a second hollow groove, and the inner cavities of the first hollow groove and the second hollow groove are rotatably connected to an I-shaped block.

[0008] Preferably, a limiting groove is formed on the surface of the support plate, and a slider is slidably connected to the inner cavity of the limiting groove. The top of the slider is fixedly connected to the bottom of the double-sided rack.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a transformer bushing lead clamping structure. (Refer to...) Figure 1-2 A transformer bushing lead clamping structure includes a transformer bushing 1, a transformer lead 2 disposed inside the inner cavity of the transformer bushing 1, and a clamping mechanism 3 disposed on the surface of the transformer lead 2. The transformer lead 2 can pass through the interior of the transformer bushing 1 and the transformer bushing 1 provides insulation protection for the transformer lead 2.

[0024] The clamping mechanism 3 includes a fixed column 301, the bottom of which is fixedly connected to the top of the transformer bushing 1. A support plate 302 is fixedly connected to the top of the fixed column 301. A hollow block 303 is fixedly connected to one side of the support plate 302. A threaded rod 304 is rotatably connected to the inner cavity of the hollow block 303. A double-sided rack 305 is threadedly connected to the surface of the threaded rod 304. The bottom of the double-sided rack 305 is slidably connected to the top of the support plate 302. A first gear 306 and a second gear 307 are rotatably connected to the top of the support plate 302. The teeth of the first gear 306 and the second gear 307 mesh with the teeth of the double-sided rack 305. A first clamping block 308 and a second clamping block 309 are provided on the surface of the transformer lead 2. One side of the first clamping block 308 is fixedly connected to the surface of the first gear 306, and one side of the second clamping block 309 is fixedly connected to the surface of the second gear 307.

[0025] The fixed column 301 can be used to support the support plate 302, so that the support plate 302 can be stably placed on one side of the transformer lead 2. The interior of the hollow block 303 can be used to place the threaded rod 304, so that the threaded rod 304 can rotate on the top of the support plate 302. When the threaded rod 304 rotates, it can drive the double-sided rack 305 to move. The first gear 306 and the second gear 307 are respectively located on both sides of the double-sided rack 305, so that when the double-sided rack 305 moves, it can drive the first gear 306 and the second gear 307 to rotate in opposite directions. The first clamping block 308 and the second clamping block 309 are respectively connected to the surfaces of the first gear 306 and the second gear 307, so that when the first gear 306 and the second gear 307 rotate, they can drive the first clamping block 308 to rotate in opposite directions. 8. The first clamping block 308 and the second clamping block 309 rotate in opposite directions together. At this time, the first clamping block 308 and the second clamping block 309, which are in reverse rotation, can clamp and fix the transformer lead 2, so that the transformer lead 2 is not easy to be displaced or detached from the transformer bushing 1 due to vibration or external force, thereby improving the stability of the transformer lead 2. Since the first clamping block 308 and the second clamping block 309 can rotate, they can clamp transformer leads 2 of different thicknesses, making the use effect better. At the same time, the threaded rod 304 is threadedly connected to the double-sided rack 305, so that the double-sided rack 305 is not easy to move, and thus the first gear 306 and the second gear 307, as well as the first clamping block 308 and the second clamping block 309, are also not easy to rotate, making it more stable.

[0026] Reference Figure 4The surface of the first gear 306 is provided with a first hollow groove 4, and the surface of the support plate 302 is provided with a second hollow groove 5. The inner cavities of the first hollow groove 4 and the second hollow groove 5 are rotatably connected to an I-shaped block 6. The interior of the first hollow groove 4 and the second hollow groove 5 can be used to place the I-shaped block 6, so that the I-shaped block 6 can limit the first gear 306, making the first gear 306 rotate more stably on the top of the support plate 302 and less likely to disengage from the double-sided rack 305. At the same time, the second gear 307 is also provided with the first hollow groove 4, the second hollow groove 5 and the I-shaped block 6, making the second gear 307 more stable.

[0027] Reference Figure 3 A limiting groove 7 is provided on the surface of the support plate 302. A slider 8 is slidably connected to the inner cavity of the limiting groove 7. The top of the slider 8 is fixedly connected to the bottom of the double-sided rack 305. The inside of the limiting groove 7 can be used to place the slider 8, so that the slider 8 can limit the double-sided rack 305, making it less likely to deviate when the double-sided rack 305 moves on the top of the support plate 302, and can only move in a straight line.

[0028] Reference Figure 3 The hollow block 303 has a third hollow groove 9 in its inner cavity. An annular block 10 is rotatably connected to the inner cavity of the third hollow groove 9. The inner cavity of the annular block 10 is fixedly connected to the surface of the threaded rod 304. The interior of the third hollow groove 9 can be used to install the annular block 10, so that the annular block 10 can be connected to the threaded rod 304. At this time, the third hollow groove 9 can limit the threaded rod 304 through the annular block 10, so that the threaded rod 304 is not easy to move when it rotates inside the hollow block 303, thereby improving the stability of the double-sided rack 305.

[0029] Reference Figure 3 A fixing block 11 is fixedly connected to one side of the threaded rod 304. The surface of the fixing block 11 is provided with anti-slip grooves 12. There are several anti-slip grooves 12. The diameter of the fixing block 11 is larger than the diameter of the threaded rod 304, so that people can easily rotate the threaded rod 304. The anti-slip grooves 12 can play an anti-slip role, so that people are less likely to slip when rotating the fixing block 11 and have difficulty rotating it.

[0030] Reference Figure 3 A reinforcing rod 13 is fixedly connected to one side of the fixed column 301. The top of the reinforcing rod 13 is fixedly connected to the bottom of the support plate 302. The reinforcing rod 13 can reinforce the connection between the fixed column 301 and the support plate 302, making the fixed column 301 more secure on the top of the support plate 302 and less prone to breakage or damage.

[0031] Reference Figure 3A rubber block 14 is provided on the surface of the transformer lead 2. The surface of the rubber block 14 is fixedly connected to the inner cavity of the first clamping block 308. The rubber block 14 has a large friction force and can replace the first clamping block 308 to contact the transformer lead 2. This makes it difficult for the transformer lead 2 to slide up and down when the first clamping block 308 and the second clamping block 309 clamp the transformer lead 2.

[0032] Working Principle: When using this device, after the transformer lead 2 passes through the inside of the transformer bushing 1, it can be placed between the first clamping block 308 and the second clamping block 309. Then, rotating the threaded rod 304 drives the double-sided rack 305 to move. The first gear 306 and the second gear 307 are located on both sides of the double-sided rack 305, so that when the double-sided rack 305 moves, it drives the first gear 306 and the second gear 307 to rotate in opposite directions. When the first gear 306 and the second gear 307 rotate, they will drive the first clamping block 308 and the second clamping block 309 to rotate in opposite directions. At this time, the first clamping block 308 and the second clamping block 309, which are rotating in opposite directions, can clamp and fix the transformer lead 2, so that the transformer lead 2 can be fixed in place. The transformer lead 2 is less prone to displacement or detachment from the transformer bushing 1 due to vibration or external force, thus improving the stability of the transformer lead 2. Furthermore, since the first clamping block 308 and the second clamping block 309 can rotate, they can clamp transformer leads 2 of different thicknesses, resulting in better performance. Simultaneously, the threaded rod 304 is threadedly connected to the double-sided rack 305, making the double-sided rack 305 less prone to movement. This, in turn, makes the first clamping block 308 and the second clamping block 309 less prone to rotation, further enhancing stability. This solves the problem that after the transformer lead 2 passes through the transformer bushing 1, during power transmission, the transformer lead 2 is prone to displacement or detachment due to vibration or external force, thus reducing the stability of the transformer lead 2.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
